PBOPELLING MECHANISM.

Specification of Letters Patent. ?afl;ent fl Artemis 1&11,

' Application filed September 8 1910 Serial No. 580,998.

To all whom it may concern..-

Be it known that I, CHARLES E. EDWARDS,

a citizen of the United States,'re'siding at Everett, in the county ofSnohomish, State of Washington, have invented a new and; usefulImprovement in Propelling Mechanisms, of which the following is aspecification. I My inventionrelates to propelling mechanisms adaptedfor use influids, and comprises certain novel parts and combinationswhich will be more fully pointed out and defined. 1

The object of-my invention is to produce an improved formof propellingmechanism, and one in which the revolving propeller is not the onlypropulsive member, .but in which the discharge from the revolving Wheelis received upon inclined blades or surfaces which are placedat such anangle f that this discharge acts thereon to propel detail showing therelative angular 'tions of the revolving and stationary b ades the bodycarrying them in the same direction as does the revolving wheel.

In the drawings accompanying this specification I have shown, 1n simpleform, a preferred mechanismillustrating the principles of, my inventionand the manner in which I may secure the desired results. Figure l is aside sectional elevation of the propelling members. Fig. 2 is =-'a frontface view or elevation. Fig. 3 is a sectional and the manner of impactofthe-fluid upon the latter. Fig. 4 is a detailshowing the constructionof the hub or center of the stationary wheel. Fig. 5 is a detailshowing. the manner of securing the itationary blades to the rim and tothe central hub.

I have discovered that by ler ofsuch shape that the fluid 1n w ich itworks will be given a considei'able gyratory or rotative efi'ect, andthen placing in the .it somewhat'jln water.

using a ropelmeaning toimply that it may not be used in water. The fluidin which it is used .may' ,be either gaseous or liquid.

The device consists of two principal parts which cooperate to producethe improved ef- "feet, namely: the propeller or equivalent means actingupon the air or fluid to giveit gyratory or rotative action, andpreferably also producing a propulsive efi'ect and with this set ofnon-rotative inclined surfaces, sails or blades, set at such an angle as.to receive the fluiddischarged from the revolving wheel or propeller,at such an angle as to act like a sail to produce a propulsive e'fiectin a direction making a relativel slight angle with that of the movement0 the fluid and in apparent opposition thereto.

I have shown as the means 'for acting upon the air to give'it the proergyratory action, a propeller wheel 1, w 'ich may be of any approvedform and turned by any convenient means, except as particularlyotherwise pointed out; As shown this proellcr is supposed to have twoblades. These lades are shaped somewhat differently from theform whichis most generally accepted as the best formior a propeller. In Fig. 3

tion. This shows that the advancing ed e 10, is i clined so asto sharplycut' the air, being rather closely approximating in its direction to aplane which is normal to theaxis of revolution.

The rear or following edge 11, of the proone of these blades is shown incross secpeller blade is, on the contrary, closely apprpximatin in itsdirection, with that of an axial p ane, the surface between theseedges-being curved so as to smoothly trendint'o 'these different angles.This makes the acting or drivingface of the propeller blades deeplyconcaved, whereby they act to drive the air rearwardly and also to giveit a considerable gyratory or rotative efi'ect. The rearward movement ofthe air produces a reactive forward-driving efi'ect. The rotative orgyratory movement of the air thus produced causes it to impinge upon theinclined,

non-rotative or fixed blades 2, after the manner indicated by the dottedline a in Fig. 3, acting upon these as sails to produce a forwardpropulsive cited. The air discharged from the wheell acts upon thesurface of the blades Q'Which is farthest from the wheel, but at suchangle as to pull them forward. These stationary blades I prefer to makein the form of a wheel which is 10- cated close behind the revolvingwheel 1. To prevent peripheral discharge of the air with out itsexerting its full eflect upon the blades 2, I prefer to inclose theseblades within a rim 3. As shown, these blades are riveted or otherwisesecured to therim by their ends, their middle portion being bent about abar 4 of the hub which extends somewhat in an axial direction, the twoends of the same piecethus forming two consecutive blades.

The hub consists of a series of the bars 4 and binding rings '5. Therings 5 should be sufiiciently small to place the blades-under tension.The bars 4 are preferably provided with grooves in their outer ends, onone side, to receive the rings 5. This construction makes a hub having aclear opening in its center.

The propeller wheel 1, I have shown as connected with an explosiveengine 6, which would probably be the preferred source of energy in mostcases. be anything which is most available and adaptable.

The rotation of an ordinary propeller.

This may, however,-

The resultant of these two effects is zero, one counterbalancing theother, wherefore, my device may be used upon aeroplanes or otherstructures without producing thereon any of this rotative effect. 4

I have found that by using this form of device the same expenditure ofpower produces a greater driving effect than can be produced by the useof a propeller alone the latter being of the most accepted design andproportion. Y

I claim:

1. A propelling wheel comprising a rim, a central hub having barsextending in a general axial direction, andaseries of blades havingtheir ends secured to the rim in an angular position, and the middleportion of each passing about one'of the bars of the hub.

2. A propelling wheel.comprising a rim, a hub consisting of a series ofbars extending in a general axial direction and rims in closing saidbars, and bladeshaving their ends secured to" the rim in an angularposition and their middle the bars of the hub.
